To evaluate the psychometric properties of the Spanish version of the short-form of the Children Perceived Oral Health Questionnaire aimed at assessing child's oral health-related quality of life of children aged 11-14 years (CPQ11-14 ). A secondary objective was to explore its screening qualities for evaluating oral health needs and immediate referral for treatment.
This cross-sectional study was conducted during August-December of 2011 in Monterrey, Mexico (n = 303 schoolchildren). The CPQ11-14 consisted of 16 items and 2 key questions. Dental caries was diagnosed by visual-tactile exam, and malocclusion by WHO index. We estimated Cronbach's alpha and Spearman's correlations and compared rank scores with the Mann-Whitney test. As we did not have a preestablished cutoff point score, we identified one with the best combination of sensitivity/specificity values using receiver operating characteristic curves.
Internal consistency was 0.85. Correlation was 0.40 (P < 0.001) between CPQ11-14 scores and self-perceived oral health rating and 0.51 (P < 0.001) between CPQ11-14 score and general well-being rating (concurrent validity). The mean score was 11.6 ± 8.6 for children in need of oral care and 8.1 ± 7.2 for those not in need of oral care (P < 0.01; discriminating validity). Sensitivity was 79.4% and specificity 48.7%; the positive and negative predictive values were 81.6% and 45.2%, respectively.
The Spanish version short-form CPQ11-14 registered acceptable psychometric properties. We were able to identify a cutoff point score with acceptable sensitivity and positive predictive value but still needs future validation before generalizing its use.
评估西班牙语版儿童口腔健康感知问卷简表（CPQ11 - 14）的心理测量特性，该问卷旨在评估11至14岁儿童与口腔健康相关的生活质量。次要目的是探索其在评估口腔健康需求及立即转诊治疗方面的筛查特性。
这项横断面研究于2011年8月至12月在墨西哥蒙特雷进行（n = 303名学童）。CPQ11 - 14由16个条目和2个关键问题组成。通过视触诊检查诊断龋齿，采用世界卫生组织指数诊断错牙合畸形。我们估计了克朗巴哈系数和斯皮尔曼相关性，并使用曼-惠特尼检验比较等级分数。由于我们没有预先设定的临界分数，我们使用受试者工作特征曲线确定了具有最佳敏感性/特异性值组合的临界分数。
内部一致性为0.85。CPQ11 - 14分数与自我感知的口腔健康评级之间的相关性为0.40（P < 0.001），CPQ11 - 14分数与总体幸福感评级之间的相关性为0.51（P < 0.001）（同时效度）。需要口腔护理的儿童平均得分为11.6 ± 8.6，不需要口腔护理的儿童平均得分为8.1 ± 7.2（P < 0.01；区分效度）。敏感性为79.4%，特异性为48.7%；阳性预测值和阴性预测值分别为81.6%和45.2%。
西班牙语版CPQ11 - 14简表具有可接受的心理测量特性。我们能够确定一个具有可接受敏感性和阳性预测值的临界分数，但在推广使用之前仍需要未来的验证。
